Types of Brain Scans-2

  • Angiography and MRI Angiography (MRA): Angiography is used to outline the presence and position of blood vessels in the brain. MRA uses a rapid series of MRI scans to follow the blood flow. It can be done with or without the injection of contrast dye.
  • Magnetic Resonance Spectroscopy (MRS): MRS produces images that show function rather than shape. This technique can show patterns of activity that may be helpful in diagnosing specific tumors and conditions. This technique may also be used to determine how advanced a tumor is.
  • Positron Emission Tomography (PET, FDG-PET): PET is not usually used for diagnosis, but it can help your doctor determine the grade of your tumor. In some cases, it may also be used to tell the difference between recurrent tumor cells, cells killed by radiation, and scar tissue.
  • Single Photon Emission Computerized Tomography (SPECT): SPECT is not usually used to diagnose brain tumors. However, it sometimes provides data that complements information captured in other scans.
  • Magnetoencephalography (MEG): This scan measures the magnetic fields created by nerve cells. No physical contact is required to record these signals. MEG is often used in combination with information from other types of scans.
